Overview
1 Overview
The TMAG5x73 devices are 3-axis (3D) linear Hall-effect sensors. These devices integrate three independent
Hall sensors in X, Y, and Z axes. A precision analog signal-chain along with integrated 12-bit ADC digitizes the
measured analog magnetic field values. The devices can be configured further to select one of two magnetic
field ranges that suits the magnet strength and component placements during system calibration. Figure 1-1
shows the TMAG5273 EVM and Figure 1-2 shows the TMAG5173 EVM.

Overview
www.ti.com
Figure 1-2. TMAG5173 Evaluation Module
The primary difference between the TMAG5273EVM and TMAG5173EVM PCBs is that only the
TMAG5273EVM has the TMAG5273 while the TMAG5173 EVM only has the automotive qualified TMAG5173
device. In addition, the PCB silkscreen on these EVMs have been updated to reference what device is on their
board. One other difference between the EVMs is that the TMAG5273EVM comes with the Rotate and Push
3D print module while the TMAG5173EVM comes with the joystick 3D print module. Table 1-1 provides the
summary of the sensitivity range options available for the A1 and A2 variants of the TMAG5x73 device. Each
device variant supports two different range options that can be selected from in software, where each device
variant has a different set of two range options that are supported. Specifically, the A1 variant of the TMAG5x73
supports either a 40-mT or 80-mT range while the A2 variant supports either a 133-mT or 266-mT range. The
appropriate range is chosen so that the range is larger than the desired maximum magnetic flux density to
sense. If both range options in a device can meet this requirement, selecting the smaller range setting would
provide the best accuracy. For example, if the maximum-sensed maximum flux density in a system is 65 mT and
the A1 variant of the device is used, select the 80-mT range of the A1 device because the 40-mT range would
not be able to sense the maximum magnetic flux density seen in the system. You can select both the 133-mT
and 266-mT range options if the A2 device is used in this example instead, but selecting the 133-mT option
provides the most accurate measurements.

2 Hardware
The EVMs are an easy-to-use platform for evaluating the main features and performance of the TMAG5x73
devices. The EVM includes a graphical user interface (GUI) used to read and write registers, as well as view and
save measurement results. The TMAG5273EVM also includes a 3D printed Rotate & Push Module to test the
common functions of angle measurement and push button with a single device. Instead of the Rotate & Push
Module, the TMAG5173EVM contains the joystick module.
The EVMs are intended to provide basic functional evaluation of the devices. The layout is not intended to
be a model for the target circuit, nor is it laid out for electromagnetic compatibility (EMC) testing. The Sensor
Controller Board (SCB) interfaces the EVM to the PC GUI. Please note that the SCB, TMAG5273EVM, and
TMAG5173EVM are all sold separately. The TMAG5x73 EVM PCBs can be broken in half across the score line
so that the TMAG5x73A1 parts of the EVM are on one PCB and the TMAG5x73A2 parts of the EVM are on the
other PCB.
2.1 Features
These EVMs include the following features:
•
•
•
•
GUI support to read and write device registers, as well as view and save measurement results
3D print rotate and push module or 3D print joystick module

3 Operation
3.1 Quick Start Setup
Figure 3-1. TMAG5x73 EVM With A1 and A2 Parts of Board Still Joined Together
To set up and use the EVM, follow these steps:
1. Gently flex the panel at the score line shown in Figure 3-1 to split the board in half for a more compact form
factor. This split provides separate boards for the TMAG5x73A1 and TMAG5x73A2 portions of the original
board.
2. Download and install the driver as a one-time step per PC: http://www.ti.com/lit/zip/sbac253
3. Attach the EVM to the Sensor Control Board (SCB). To evaluate the TMAG5x73A1 on the EVM, attach
header J1 of the Sensor Controller board to header J1_A1 of the EVM (see Figure 4-1). To evaluate the
TMAG5x73A2 on the EVM, attach header J1 of the Sensor Controller board to header J1_A2 of the EVM
(see Figure 4-2).
4. Use a USB cable to connect the SCB to a PC
a. Insert the micro USB cable into the USB receptacle J2 that is on the SCB Controller onboard.
b. Plug the other end of the USB cable into a PC.
5. Access the GUI in either the Google Chrome® or Firefox® browser by clicking on the following link: https://
dev.ti.com/gallery/info/7472171/TMAG5x73EVM_GUI/ver/2.0.0/
6. To quickly view results on the GUI, do the following:
a. Modify the MAG_CH_EN bits in the SENSOR_CONFIG_1 register to enable the desired channels
to read from. The GUI has drop-down boxes to configure these bits when the SENSOR_CONFIG_1
register is selected in the register tab of the GUI.
b. Select the desired result plots under the Results to collect/show box in the Results Data tab, and press
Collect Data to trigger the read.
These two steps are the minimum steps needed to see results in the GUI. However, this assumes that the
default register settings are used for the other registers. For more custom settings, modify the corresponding
register bits according to the system requirements.
7. Apply a magnetic field to the sensor by doing one of the following:
a. Wave the included handheld magnet around the sensor.

4.1 Setup
4.1.1 Driver Installation
Download and install this driver: http://www.ti.com/lit/zip/sbac253. This is a one-time step per computer. Unzip
the folder and run the .exe file with administrator privileges.
4.1.2 Firmware
The firmware must be flashed onto the SCB to properly communicate to the TMAG5x73EVMs. After flashing
the SCB with the TMAG5x73EVM, the firmware does not have to be reflashed on the SCB as long as the
firmware is not erased or replaced with the firmware for a different EVM. If the firmware is erased or replaced,
the TMAG5x73EVM firmware must be flashed onto the SCB again to communicate to the TMAG5x73EVMx. The
latest version of the firmware can be downloaded from: https://www.ti.com/lit/zip/sbac295.
4.1.2.1 Updating Firmware on SCB
Follow these steps to install the firmware.
1. Configure the MCU on the SCB to be in Device Firmware Update (DFU) Mode. DFU mode can be entered
manually through one of the following methods while the SCB is powered on:
a. Through software:
• Send the command "bsl" on the SCB's USB Serial (COM) port.
b. Though hardware (with the EVM removed):
• Short the two test points labeled DFU (see Figure 4-3) with a pair of tweezers (or wire) while pressing
the RESET button. If this is done correctly, LED D1 on the SCB should turn off while the LED D5 (the
power LED) remains on. If LED D1 is still on, the GUI firmware is still active and the device has not
entered DFU mode.
Figure 4-3. Test Points Used to Enter DFU Mode Manually
2. With the MCU in DFU mode, the firmware can now be uploaded through the USB
Bootstrap Loader (BSL) scripter tool and batch file by doing the following:
a. Download the firmware package and BSL scripter tool from the EVM page, or use the link: https://
www.ti.com/lit/zip/sbac295
b. Unzip the firmware folder and run the .bat file.
c. Unplug the USB cable from the PC after the firmware is flashed, then plug the cable back in to reset the
SCB.

EVM Operation
4.2 Rotate and Push Demo
The TMAG5273EVM comes with the rotate and push 3D print; however, this 3D print could also work with the
TMAG5173 since both devices use the same magnetic range. To use the Rotate & Push Demo, follow these
steps:
1. Attach the Rotate & Push Module to the EVM (see Figure 4-10 for an example on how this module is
connected to the A1 part of the EVM).
Figure 4-10. Rotate & Push Module on EVM
2. In the GUI register page:
a. Select the DEVICE_CONFIG2 register and check the following:
i. Make sure the drop-down menu option for the OPERATING_MODE register bits says 00b = Standby
Mode
ii. Make sure the drop-down menu option for the TRIGGER_MODE register bits says 0b=Conversion
Start at I2C Command Bits
b. Click the SENSOR_CONFIG1 register and select the 0011b= X, Y channel enabled option under the
MAG_CH_EN drop-down menu to enable the X and Y channels.
c. Click the SENSOR_CONFIG2 register and set the X_Y_RANGE drop-down menu to one of the below
options (note that the same range option will be selected for the X and Y axes; however, the Z axis
range can be set independently of the x and y axes range setting):
i. If the TMAG5273A1 part of the EVM is connected to the SCB, select the 1b = ±80 mT
(TMAG5273x1)/ ±266mT (TMAG5273x2) option. This will ensure that the 80-mT variant is selected
for the TMAG5273A1. Note that the demo will not work with the 40-mT range because the magnetic
flux density produced by the Rotate & Push Module is greater than 40 mT, which is why the 80-mT
range is selected.
ii. If the TMAG5273A2 part of the EVM is connected to the SCB, select the 0b = ±40 mT
(TMAG5273x1)/ ±133mT (TMAG5273x2) option. This will ensure that the 133-mT range option is
selected. The 266 mT could also be used here instead, but the results using this range would not be
as good as the results with the 133-mT range.
d. Optional: Click the SENSOR_CONFIG2 register and set the ANGLE_EN drop-down menu to 01B = X
1ST, y 2ND. Performing this step enables the TMAG5273’s angle measurement calculation.
e. Set the Auto Read at the top of the register map to As fast as possible.
3. Go to the Rotate & Push tab inside the plots page (see Figure 4-11).

4.3 Joystick Demo
The TMAG5173EVM comes with the Joystick 3D print; however, this 3D print could also work with the
TMAG5273 since both devices use the same magnetic range. To use the joystick demo, follow these steps:
1. Attach the joystick module to the EVM. See Figure 4-15 for an example on how this module is connected to
one of the two TMAG5173 EVM parts.

a. Select the DEVICE_CONFIG2 register and check the following:
i. Make sure that drop-down menu option for the OPERATING_MODE register bits says 00b =
Standby Mode (starts new conversion at trigger event)
ii. Make sure that drop-down menu option for the TRIGGER_MODE register bits says 0b=Conversion
Start at I2C Command Bits
b. Click the SENSOR_CONFIG1 register and select the 0011b= X, Y channel enabled option under the
MAG_CH_EN drop-down menu to enable the X and Y channels. You can also select the 0111b= X,
Y, Z channel enabled option to enable the Z channel, but only the X and Y channels are required
to observe the effect of the motion of the joystick. If the Z channel is enabled, remember that this
channel sees larger fields than the X and Y channel. Select the 1b = ±80 mT (TMAG5x73A1)/ ±266mT
(TMAG5X73A2) option under the Z_RANGE register bit drop-down menu to ensure the Z_RANGE bit in
the SENSOR_CONFIG2 register is set to 1.

i.
Note that different joysticks may have different magnetic readings for a specific joystick position due
to differences in the installation position of the spherical magnet within the joystick; however, this can
be dealt with by mapping the different joystick positions to the magnetic flux density readings during
calibration, similar to the approach shown in this video: https://training.ti.com/designing-joystickshall-effect-sensors
4. Press the STOP COLLECT button to stop collecting data.
5. After testing a particular TMAG5x73 device variant, make sure to first disconnect the SCB USB cable
from the PC before connecting the SCB to another part of the EVM board associated with the other
TMAG5x73 device variant. After disconnecting the cable, the part of the EVM board associated with the
other TMAG5x73 variant should be connected to the SCB before reconnecting the SCB USB cable to the
PC.
4.4 Direct EVM Serial Communication
If desired, the SCB can communicate directly with the EVM without the use of the GUI through the USB serial
(COM) port. Simply send the desired command string over the serial port and receive the results. This is useful
for interfacing the EVM with custom setups/scripts/GUIs. Note that the TMAG5x73EVM must be connected to
the SCB to receive any command responses from the SCB.
To read and write registers, follow the below format:
•
Read register command format: rreg ADR
– Where ADR is the address in hex, and rreg is always lower case
– Register addresses can be in upper or lower case, and do not need to be led by "0x". 0 padding register
addresses is also optional. For example, to read register address 0xE, some valid commands include:
• rreg e
• rreg 0E
• rreg 0x0E
– When "0x" is used, the "x" must be lower case.
– Figure 4-18 is an example response to this command:
Figure 4-18. Example Register Read Response
•
The number to the right of value represents the value read from the register. Note that this value is
represented in decimal form and not hexadecimal.
Write register command format: wreg ADR VAL
– Where ADR and VAL are in hex, and wreg is always lower case
– Register addresses and values can be in upper or lower case, and do not need to be led by "0x". 0
padding register addresses and values is also optional. For example, to write register address 0x0 with the
value 4, some valid commands include:
• wreg 0 4
• wreg 00 0x4
• wreg 0x00 0x04
– When "0x" is used, the "x" must be lower case.
– Figure 4-19 is an example response to this command:

associated with the version of the firmware loaded on the SCB.
– Figure 4-20 is an example response to this command:
Figure 4-20. Example Firmware Revision Command Response
– The date and time obtained from this command is the same date and time that appears in the GUI’s About
screen (see Figure 4-21). Click the About option under the GUI's Help menu to view the About screen.

BSL command format: bsl
– This command puts the device in BSL mode, which is necessary before reflashing the SCB firmware. An
alternative to entering BSL mode is to do it in hardware as described in step 1b of Section 4.1.2.1. Before
BSL is entered, LED D1 is on. If BSL mode is successfully entered, LED D1 is turned off so that only
the Power LED (LED D5) is on. After entering BSL mode, the device does not accept any of the above
commands.
– Figure 4-22 shows an example response to this command:
Figure 4-22. BSL Command Response
Trigger conversion command format: rreg 0
– If the device is in standby mode and new conversions are set to be triggered through I2C, doing a register
read at register 0 automatically starts a new set of conversions.

Circuitry
5 Circuitry
This section summarizes the EVM subsystems and their components.
5.1 TMAG5x73 EVM Components
This section describes the main TMAG5x73 devices and supporting components. The component footprints that
are duplicated on both the A1 and A2 parts of the board, have an _A1 or _A2 appended to the end of their
component names to indicate whether the component is on the A1 or A2 part of the board. With the exception
of components U1_A1 and U1_A2, which correspond to different TMAG5x73 device variants, all other _A1
components use the same components as the corresponding _A2 components.
The EVM has the following components:
•
•
•
•
•
U1_A1 is the TMAG5x731A1 device on the A1 part of the board and U1_A2 is the TMAG5x73A2 device on
the A2 part of the board.
C1_A1, C1_A2, C2_A1, and C2_A2 are bypass capacitors that are placed near the sensor to help mitigate
power-supply noise and provide current quickly to the device when needed.
J1A_A1 and J1B_A1 are the main header pins that connect the digital and power pins of the TMAG5x73A1
to the SCB Controller. Similarly, J1A_A2 and J1B_A2 are the main header pins that connect the digital and
power pins of the TMAG5x73A2 to the SCB controller.
Resistors R1_A1 and R1_A2 connect the 3.3-V rail from the SCB board to the TMAG5x73A1 and
TMAG5x73A2. Remove these resistors if you wish to power the TMAG5273 from a different power source.
Resistors R2_A1 and R2_A2 are the pullup resistors on the SCL pin of the TMAG5x73 devices. Similarly,
resistors R3_A1 and R3_A2 are the pullup resistors on the SDA pin of the TMAG5x73 devices. R4_A1 and
R4_A2 are the pullup resistors on the interrupt pin of the TMAG5x73 devices.
5.2 SCB LEDs
Three LEDs on the SCB board are used to indicate status:
•
•
•
LED D5 is a green LED that is ON whenever the USB is connected to the SCB, which would also power the
SCB and any connected TMAG5x73 devices.
LED D4 is a red LED that indicates the status of the INT pin of the connected TMAG5x73 device. The SCB
firmware polls the state of the TMAG5x73 INT pin and turns on the LED D4 when the TMAG5x73 INT pin
is asserted low. This LED is an easy way to visually observe the state of the TMAG5x73 INT pin if the
TMAG5x73 is configured to either provide interrupts to indicate that data is ready or if it is configured to
indicate that a user-defined magnetic threshold has been surpassed.
LED D1 is a green LED that indicates that the TMAG5x73 EVM firmware is loaded on the board and the EVM
is not in DFU mode. If the EVM enters DFU mode, whether through software or hardware, this LED is turned
off while the LED D5 remains on.

STANDARD TERMS FOR EVALUATION MODULES
1.
Delivery: TI delivers TI evaluation boards, kits, or modules, including any accompanying demonstration software, components, and/or
documentation which may be provided together or separately (collectively, an “EVM” or “EVMs”) to the User (“User”) in accordance
with the terms set forth herein. User's acceptance of the EVM is expressly subject to the following terms.
1.1 EVMs are intended solely for product or software developers for use in a research and development setting to facilitate feasibility
evaluation, experimentation, or scientific analysis of TI semiconductors products. EVMs have no direct function and are not
finished products. EVMs shall not be directly or indirectly assembled as a part or subassembly in any finished product. For
clarification, any software or software tools provided with the EVM (“Software”) shall not be subject to the terms and conditions
set forth herein but rather shall be subject to the applicable terms that accompany such Software
1.2 EVMs are not intended for consumer or household use. EVMs may not be sold, sublicensed, leased, rented, loaned, assigned,
or otherwise distributed for commercial purposes by Users, in whole or in part, or used in any finished product or production
system.
2
Limited Warranty and Related Remedies/Disclaimers:
2.1 These terms do not apply to Software. The warranty, if any, for Software is covered in the applicable Software License
Agreement.
2.2 TI warrants that the TI EVM will conform to TI's published specifications for ninety (90) days after the date TI delivers such EVM
to User. Notwithstanding the foregoing, TI shall not be liable for a nonconforming EVM if (a) the nonconformity was caused by
neglect, misuse or mistreatment by an entity other than TI, including improper installation or testing, or for any EVMs that have
been altered or modified in any way by an entity other than TI, (b) the nonconformity resulted from User's design, specifications
or instructions for such EVMs or improper system design, or (c) User has not paid on time. Testing and other quality control
techniques are used to the extent TI deems necessary. TI does not test all parameters of each EVM.
User's claims against TI under this Section 2 are void if User fails to notify TI of any apparent defects in the EVMs within ten (10)
business days after delivery, or of any hidden defects with ten (10) business days after the defect has been detected.
2.3 TI's sole liability shall be at its option to repair or replace EVMs that fail to conform to the warranty set forth above, or credit
User's account for such EVM. TI's liability under this warranty shall be limited to EVMs that are returned during the warranty
period to the address designated by TI and that are determined by TI not to conform to such warranty. If TI elects to repair or
replace such EVM, TI shall have a reasonable time to repair such EVM or provide replacements. Repaired EVMs shall be
warranted for the remainder of the original warranty period. Replaced EVMs shall be warranted for a new full ninety (90) day
warranty period.
